Revive N means for one TARGET PLAYER to move exactly N Cards from their Limbo (the Origin Zone) to their Field (the Destination Zone). Refer to Zones.

The Effect Syntax is:

PLAYER Revive N, They Select Cards, They Select Spot 

"Revive" by itself means:

YOU Revive 1, You Select Cards, You Select Spot 

Cards are moved one at a time from the Limbo zone to the Field zone, until N cards have been moved. Only Unit Cards may be selected and Spots must be Vacant to receive each Unit. If at any time insufficient cards exist in the Limbo zone, there are no Cards, or all Spots are Occupied, then this movement effect ends. A Movement Effect always Resolves, even if the Limbo zone is Empty to begin with.

Before a Card moves from the Limbo zone, Leave Zone Triggers happen. These effects may replace the Destination Zone.

After a Card moves into the Field zone, Enter Zone Triggers happen. These effects may further Move the card.

See also Movement. When the Destination Zone is the Base or Field, an Effect may also include Placement.
